Abstract

A process for the preparation of a catalyst system includes the steps of combining a Lewis base, an organic compound having at least one functional group containing active hydrogen, and an organometallic component with a particulate support material to provide an intermediate composition, and then combining the intermediate composition with one or more metallocene compound. The catalyst system is advantageously used for olefin polymerization.

Description

BACKGROUND

[0001] 1. Field of the Invention

[0002] The present invention relates to a process for preparing a catalyst system for olefin polymerization which is obtainable by bringing at least one metallocene, at least one organometallic compound, at least one compound that is obtainable by a reaction of an organometallic compound with an organic compound bearing a functional group containing active hydrogen, at least one Lewis base and at least one support into contact with one another, to catalyst systems obtainable by this process, to the use of these catalyst systems for olefin polymerizations, to a process using such catalyst systems for polymerization and copolymerisation of olefins and to polymers which are prepared using such catalyst systems.

[0003] 2. Background of the Art

[0004] Processes for preparing polyolefins using soluble, homogeneous catalyst systems comprising organic transition metal compounds such as metallocene complexes are well known (Angew. Chem. 1995, 107, 1255-128...
